And there is a LOT of information and pictures of Plymouth Rocks on Crohio.com - click on the Plymouth Rock club link... Join up and get to know folks, they're nice people for the most part.
Your girls comb is well over the five points, that they look for, has that wavy and a depression and may lay over even as she grows. In comb alone - those things are not show quality. Rodriguez gave you good pictures for the reference between show barring and production/hatchery barring. She is smallish for a large fowl. As you sort your growing out babies - sort for cleaner barring, bigger birds and straight, closer to five point comes and you'll be started in the right direction.

Crohio plymouth rocks does have a copy of the 1915 Plymouth Rock Standard for all colors. It hasn't changed all that much over the years.
You can also buy the APA breed standards in black and white for 14.00 on their site. Don't bother buying the color one this year - there's a new addition supposedly out this Fall, so if in color - wait til the new one comes out. It's worth having. Though color runs a good bit more.
